Fuente de alimentación MEAN WELL SCW20A-12, 20 W de potencia de salida, 12 V

MEAN WELL SCW20A-12 is a compact DC-DC converter designed for PCB mounting that delivers a regulated 12 Vdc output at up to 1.67 A from a 9–18 Vdc input range. Housed in a DIP through-hole package, this 20 W power adapter/inverter is intended for low-power electronic equipment where a stable DC supply is required. The unit meets RoHS requirements and is offered in bulk quantities for manufacturing and installation projects.

Advantages

The converter provides a stable 12 V output with up to 20 W of power in a small DIP through-hole form factor suitable for PCB integration. Its wide 9–18 V input range supports varied source voltages, and the regulated output reduces the need for additional circuitry. The compact size and through-hole mounting make it straightforward to install in custom boards and prototypes. RoHS compliance ensures it meets common environmental and regulatory requirements for electronic assemblies.

Suitable for

• LED modules and small lighting systems
• Embedded control units and single-board controllers
• Communication devices and modems with 12 V supply requirements
• Industrial sensors and monitoring modules
• Small battery-powered systems requiring voltage conversion

How to use

Mount the unit onto the PCB using the through-hole DIP pins and ensure proper solder joints for reliable electrical and mechanical connection. Verify the input supply voltage is within the 9–18 Vdc range before connecting the converter. Observe correct polarity at the input and output terminals. After connection, measure the output with a multimeter to confirm 12 Vdc under expected load conditions. Provide adequate PCB copper area or through-hole thermal paths if the converter is expected to operate near its 20 W limit to assist heat dissipation.
